Popis
Shrnutí:The event-triggered security control and fault detection for nonlinear systems, in which the output signals are wirelessly transmitted to the control and detection module, is investigated in this paper. In particular, quantization before data transmission and deception attacks during data transmission are considered. To ease the data transmission pressure of wireless networks, a dynamic event-triggered protocol is proposed. Specifically, the triggering threshold changes in accordance with the system state. A stochastic sequence is introduced for modelling the time of occurrence of cyber-attacks within an insecure communication environment. By taking the dynamic event-triggered protocol, signal quantization and randomly occurring deception attacks into account, an integrated dynamic output feedback controller and fault detection filter module is developed. With the proposed design, stochastic stability is obtained, while the expected levels of security control performance and detection performance are also guaranteed. Novel algorithms are proposed for determining the parameters of the controller, filter and dynamic event-triggered protocol. A practical example is given to demonstrate the effectiveness of the proposed design idea.
